Bench-Scale Renewable Ammonia Plant

The bench-scale renewable ammonia plant (BSRAP) is a vision of future distributed-scale ammonia production
of utility to either the agricultural producer or electric power generators where NOx remediation technology
is required. The BSRAP is a highly flexible modular test system that allows for testing of feedstocks and
processes by which the feedstock in question can be converted to a higher-value commodity such as anhydrous
ammonia. The original feedstock for which the system was designed was biogas from an anaerobic digester.
Cutting-edge technologies have been tested as a means to enable cost-effective and efficient production
of both renewable hydrogen and ammonia. The plant consists of six different operating units.

Data Collection

The BSRAP is fully instrumented and capable of either manual or automated control. The length of a test program can be virtually
limitless because of the ruggedness of design and ability to conduct unattended operation.
